HA Autoclaveable Pressure Sensor

New product
More info

Anderson-Negele’s Autoclaveable HA Sanitary Pressure Transmitter is specifically designed for critical measurements in applications where equipment is autoclaved. Developed from the highly stable “Mini” HA Pressure Transmitter, the Autoclavable HA takes the versatility of a small form factor transmitter to the next level by withstanding the stress of the autoclave environment. Its one-piece stainless steel package design incorporates a transducer and electronic circuitry to convert pressure and/or vacuum to a proportional 4-20 mA signal.

Process pressure measurement in pipes and vessels, process temperatures up to 150°C (302°F)
